Not necessary at all, as you say, but it's never hurt. I'm a smallish, nerdy, computer programmer. On a camping trip this weekend I tossed a football around with a guy I might never have chatted with otherwise. I'm so thankful I learned how to do that when I was a small child. My parents were right to push me in that direction when I might have preferred staying in with my Apple II.
